Technical field
[0001] The application relates generally to a control system for controlling the feed of
a solid fuel in a combustion process.
Background
[0002] Some of the solid fuel, e.g. peat, woodchips or sawdust, arriving at heating and
power facilities for use in a combustion process, is unloaded on the field from where
the fuel is loaded by a bucket loader onto a conveyor either directly or in such a
way that various types of fuel are blended with visual inspection, e.g. in amongst
bark is admixed dry cutter shavings.
[0003] On the other hand, some of the incoming fuel is unloaded directly into the facility's
reception pockets, wherefrom it is conducted on conveyors into silos according to
fuel type information inputted into the system with a truck scale by a fuel supplier
or without more precise information about the type of fuel. Alternatively, all fuels
arrive at a reception station, wherefrom the fuel proceeds into storage silos or buildings.
Fuel fractions are blended at reception on the basis of just type information, or
the mixing is carried out in storage spaces where the fuel is unloaded into a stack
and removed with transverse screws from a bottom of the stack. In a storage space,
peat can be placed on one side of the storage space and all types of wood chips elsewhere,
but the most common practice is to place all fuel types in disarray.
Summary
[0005] It is one objective of the invention to eliminate some of the problems of the prior
art and to control a solid fuel combustion process in view of reducing the quality
fluctuations of a solid fuel to be supplied into a boiler, thereby facilitating e.g.
the regulation of a combustion process, improving the efficiency of an incineration
plant, reducing operating and maintenance costs with a declining corrosion effect,
as well as reducing greenhouse, CO, NOx and the like emissions.
[0006] The one objective of the invention is attained with the subject-matter according
to the independent claim.
[0007] The control system according to one embodiment of the invention is a control system
according to claim 1.
[0008] The term solid fuel is used e.g. in reference to biofuels to be burned in heating
and/or power facilities, e.g. wood chips, e.g. whole tree chips, forest residue chips,
stump chips and recycled woodchips; wood dust, e.g. sawdust and cutter swart; bark,
peat, recycled fuels, e.g. REF, RDF and SRF; wood briquettes, wood pellets, field
biomasses, e.g. straw and reed canary grass; coal and side flows of pulp and paper
industry.
[0009] The term communications link is used e.g. in reference to a wired and/or wireless
communication connection between devices capable of data connection. The wired link
can be e.g. a USB (Universal Serial Bus) link, an Ethernet connection or some other
link with an ability to communicate signals via wires, fibers or other landline media.
The wireless link can be e.g. a short range wireless connection, e.g. a Bluetooth,
Wi-Fi, wireless USB or some other wireless connection. The communications link can
be established by means of at least one of the following communication networks; Internet,
extranet and intranet; a mobile communication network which uses e.g. GSM, EDGE, UMTS,
CDMA or WCDMA technology; or a public switched telephone network.
[0010] The term online measurement is used e.g. in reference to continuous measuring devices
which make use of X-ray, microwave, infrared and magnetic resonance technology. In
addition, reference can be made e.g. to a measurement based on devices using electrical
capacitance or conductance, ultrasound acoustic, laser and video imaging.

vary in number but if peat is employed as a fuel, it can have its own pocket.
[0015] The facility 101 comprises a boiler 102 for burning fuel and producing energy.
[0016] The facility 101 may further comprise conveying means 105, e.g. belt, chain, screw,
scraper, lamella or elevator (belt-chain) conveyors, vibratory feeders or stoker dischargers,
for conveying fuel from the unit 106a, 106b, 106c towards the boiler 102 after being
removed from the unit 106a, 106b, 106c e.g. with drag chain and/or stoker dischargers.
[0017] The facility 101 further comprises at least one fuel silo 104, 108a, 108b between
the unit 106a, 106b, 106c and the boiler 102. The storage silo (storage) 104 is used
for the interim storage of fuel prior to its transfer into at least one feeding silo
108a, 108b. The feeding silo(s) 108a, 108b is (are) used for storage of fuel prior
to its delivery into the boiler 102.
[0018] Each silo 104, 108a, 108b comprises feeding means 110a, 110b, 110c, e.g. drag chain
and/or belt conveyors, for supplying the silo 104, 108a, 108b with fuel arriving by

[0019] Each silo 104, 108a, 108b comprises discharging means 112a, 112b, 112c, e.g. a discharge
screw(s), and stoker and/or drag chain bottom dischargers present on a bottom of the
silo 104, 108a, 108b for conveying fuel onto the discharging screw(s) in view of discharging
fuel from the silo 104, 108a, 108b onto the conveying means 105.
[0020] In addition, each silo 104, 108a, 108b may comprise separate or joint control means
capable of communicating by way of a communications link to the feeding means 110a,
110b, 110c and to the discharging means 112a, 112b, 112c.
[0021] The facility 101 may further comprise removal means 114c, e.g. a removal gate or
a screw conveyor with a reversible discharge direction, for clearing the conveying
means 105 or the combustion process of fuel which for some reason is rejected as unacceptable
for the combustion process.
[0022] The facility 101 may further comprise control elements for the removal means 114c,
which are capable of communicating by way of a communications link.
[0023] The system 100 comprises a control unit 120 which is capable of communicating in
the system 100 by way of a communications link, e.g. wirelessly by way of a mobile
communication network as shown in the figure.
[0024] The system 100 further comprises at least one set of online quality measuring instruments
130a, 130b, 130c, 130d, which are capable of communicating with the unit 120 by way
of a communications link. Making use of the online quality measurement of fuel enables
an enhancement of the facility 101 in terms of its production.
[0025] The system 100 may comprise merely the first set of measuring instruments 130a, e.g.
X-ray measuring instruments, which are installed in connection with the conveying
means 105 between the unit 106a, 106b, 106c and the silo 104. The measuring instruments
130a can be installed as shown in the figure, or by 25 having the same installed in
connection with each of the designated conveyor means 105 coming from each pocket
of the unit 106a, 106b, 106c.
[0026] The measuring instruments 130a monitor the fuel (a batch of fuel) carried on the
conveying means 105 by continuous measuring and supply the unit 120 with fuel-related
measurement data obtained from the measurement.
[0027] The unit 120 receives measurement data from the measuring instruments 130a and is
able to continuously calculate from the measurement data at least one of the fuel
quality criteria (quality data): type of fuel, moisture content, foreign matter content,
ash content, at least one element concentration, energy content, density, mass, and
fragment size.
[0028] In addition, the unit 120 may control the removal means 114c by way of a communications
link for removing the fuel measured with the measuring instruments 130a, on the basis
of the received measurement data and the at least one calculated criterion thereof,
from the conveying means 105 prior to feeding it into the silo 104.
[0029] The unit 120 is additionally able to establish a real-time content model for the
silo 104, e.g. two- or three-dimensional model, about its fuel distribution on the
basis of at least one of the aforesaid criteria, e.g. the energy content, to maintain
the established content model and to update it in real time according to fuel being
supplied and discharged.
[0030] In the content model, it is possible to utilize not only the at least one criterion
but also e.g. at least one of the following data: operating data for the conveyor
means 105, identification data for fuel loads, e.g. information about a supplier,
a type and/or a location, information about a truck scale used for determining the
amount of a fuel load and other possible information obtainable from auxiliary measurements,
e.g. operating data for a belt scale and/or other equipment.
[0031] The unit 120 further controls feeding means 110c of the silo 104 by way of a communications
link for feeding the measured fuel from the conveying means 105 into the silo 104.
Based on the content model and the measurement data received from the measuring instruments
130a, the feeding means 110c are supplied with control information regarding to which
part of the silo 104 the fuel is to be delivered.
[0032] In addition, the unit 120 controls discharging means 112c by way of a communications
link for discharging fuel onto the conveying means 105 extending from the silo 104
to the silo 108a, 108b. Based on the content model and the possibly received measurement
data, the discharging means 112c are 30 supplied with control information regarding
from which part of the silo 104 the fuel is to be discharged onto the conveying means
105.
[0033] Moreover, the unit 120 is able to receive information about upcoming fuel loads,
e.g. information about suppliers, fuel type, place of delivery, and scale data.
[0034] The system 100 may comprise second measuring instruments 130b, e.g. X-ray measuring
instruments, which are installed in connection with the conveying means 105 between
the silo 104 and the silo 108a, 108b.
[0035] The unit 120 may receive measurement data from the measuring instruments 130b and
it may calculate continuously from the discussed measurement data at least one of
the aforesaid criteria, e.g. the energy content.
[0036] In addition, the unit 120 is able to establish a real-time content model for each
silo 108a, 108b, e.g. a two- or three-dimensional model, about its fuel distribution
on the basis of the at least one aforesaid criterion, to maintain the established
content model and to update it in real time according to fuel being supplied and discharged.
[0037] The unit 120 further controls the feeding means 110a, 110b for the silo 108a, 108b
by way of a communications link for feeding fuel into the silo 108a, 108b. Based on
the content model and the measurement data received from the measuring instruments
130b, the conveying means 105 are supplied with control information regarding into
which silo 108a, 108b the fuel to be conveyed and the feeding means 110a, 110b are
supplied with control information regarding to which part of the silo 108a, 108b the
fuel is to be delivered.
[0038] In addition, the unit 120 controls the discharging means 112a, 112b of the silo 108a,
108b by way of a communications link for discharging fuel onto the conveying means
105 extending from the silo 108a, 108b to the boiler 102. Based on the content model
and based on measurement data possibly received from the measuring instruments 130b,
the discharging means 112a, 112b are supplied with control information regarding from
which part of the silo 108a, 108b the fuel is to be discharged onto the conveying
means 105.
[0039] Controlling the feeding and discharging means 110a, 110b, 110c, 112a, 112b, 112c
of each silo 104, 108a, 108b enables an improvement in the quality of a fuel passing
into the boiler 102, i.e. an effort to provide a fuel with quality as consistent as
possible, whereby it is optimal from the standpoint of a combustion process.
[0040] Also, the control enables an optimization of fuel mixtures. The optimization of mixture
ratios is a way of avoiding the feeding of expensive additives, e.g. elemental sulfur
and sulfates, into the boiler 102 in case there is a risk of chlorine-induced corrosion.
[0041] In addition, the control enables a protection of the boiler 102 by avoiding undesired
fuel blends which increase the corrosion risk.
[0042] The control further provides an ability to maintain the boiler 102 and a turbine
in optimal operation (boiler-turbine balance), to reduce emissions and to improve
the efficiency of a combustion process.
[0043] By virtue of its on line measurement, the system 100 is capable of supplying and
controlling the supply of fuel.
[0044] In addition, the unit 120 is able to transmit, by way of a communications link, fuel
demand information based on a content model of the silo 104 and/or the silo 108a,
108b to a unit in charge of the supply of fuel, e.g. to at least one supply program
of the unit 120 or some other computer. The demand information makes it possible to
report which fuel fractions are needed in the facility 101 for maintaining an optimal
fuel distribution.
[0045] The unit 120 may further receive predictions from fuel supply programs regarding
upcoming fuel loads, thereby enabling the establishment of demand data also on the
basis of e.g. predictions and a content model.
[0046] The system 100 may comprise third measuring instruments 130c, 130d, e.g. Xray measuring
instruments, which are installed in connection with the conveying means 105 between
each silo 108a, 108b and the boiler 102.
[0047] In addition, the system 100 may comprise control means, which control the combustion
process of the boiler 102 and which are capable of communicating by way of a communications
link.
[0048] The unit 120 is able to receive measurement data from the measuring instruments 130c,
130d and is able to calculate continuously from the discussed measurement data at
least one of the aforesaid criteria, e.g. the energy content.
[0049] In addition, the unit 120 is able to transmit information pertinent to measurement
data received from the measuring instruments 130c, 130d, e.g. measurement data or
information about a calculated criterion, to the control means of the combustion process
of the boiler 102.
[0050] Fig. 1 b shows a facility 101 similar to that of fig. 1 a but missing the silo 104
serving as an intermediate storage.
[0051] The system 100 only comprises measuring instruments 130a, e.g. X-ray measuring instruments,
which are installed in connection with the conveying means 105 between the unit 106a,
106b, 106c and the silo 108a, 108b.
[0052] The measuring instruments 130a measure continuously a fuel carried on the conveying
means 105 and supply the unit 120 with fuel-related measurement data obtained from
the measurement.
[0053] The unit 120 receives measurement data from the measuring instruments 130a and is
able to calculate continuously from the discussed measurement data at least one the
aforesaid criteria, e.g. the energy content.
[0054] The unit 120 is able to control the discharge means 114c, to establish a content
model about its fuel distribution on the basis of at least one of the aforesaid criteria,
e.g. the energy content, to maintain and update the established content model as in
the system 100 of fig. 1.
[0055] In addition, the unit 120 is able to control feeding means 11 Oa, 11 Ob and discharging
means 112a, 112b for the silo 108a, 108b as in the system 100 of fig. 1.
[0056] The unit 120 is further able to transmit fuel demand information based on a content
model of the silo 108a, 108b as in the system 100 of fig. 1.
[0057] By virtue of its on line measurement, the system 100 is capable of controlling the
supply of fuel for the facility 101.
[0058] The system 100 is easy to install in old facilities 101, its operation is not restricted
by fuel employed in the facility 101, and it is not bound up with the employed measuring
method.
[0059] By virtue of the system 100, the facility 101 has accurate initial data about the
quality of fuel, thus enabling to make an optimal fuel mixture of consistent quality.
The quality fluctuations of fuel, regarding e.g. moisture, complicate adjustment of
the boiler 102, whereby the bed temperatures fluctuate with resulting emission spikes,
the efficiency suffers, and the corrosion risk increases. By virtue of the system,
it is further possible to obviate production losses e.g. in winters when the entire
production capacity of the facility 101 is needed.
[0060] Fig. 2 shows functional units 240, 242, 244, 246 for a control unit (control device)
220 that may comprise at least one computer.
[0061] The unit 220 comprises a processor unit 240, which comprises at least one processor
and which enables the execution of instructions, defined e.g. by a user or some application
program, and the processing of data.
[0062] In addition, the unit 220 comprises a memory unit 242, which comprises at least one

from the unit 220.
[0064] The user interface unit 246 may comprise at least one of the following: a keyboard,
functional keys, a display, a touchpad, a touch screen, and a microphone/speaker unit.
[0065] The memory unit 242 may comprise an application 254 controlling operation of the
data transfer unit 244, and an application 256 controlling operation of the user interface
unit 246, and the memory unit comprises an application (computer program) 258 intended
for controlling operation of the unit 220.
[0066] In addition, the memory unit 242 may comprise an application 260 controlling operation
of the online quality measuring instruments 230 in the event that the 30 measuring
instruments 230 are remote-controlled from the unit 220.
[0067] The application 258 controls operations of the unit 220 and possibly other equipment
102, 104, 108a, 108b, 230 in the feed of a solid fuel in a combustion process when
it is carried out in the unit 220. The application 258 comprises a reception code
which uses the data transfer unit 244 to receive from 5 the measuring instruments
230, by way of a communications link, online measurement data regarding a fuel coming
in from the fuel unit 106a, 106b, 106c, and a control code which uses the data transfer
unit 244 to control, by way of a communications link, the feeding means 110a, 110b,
110c for delivering the measured fuel into the silo 104, 108a, 108b on the basis of
its content model and measurement data.
[0068] The application 258 can be stored not only in the memory unit 242 of the unit 220
but also in a computer program product, which is a computer-readable data transfer
medium, e.g. a CD disc or a USB flash drive, and which comprises a computer program
code intended to be run on a computer.
[0069] The memory unit 242 and the application 258, jointly with the processor unit 240,
enable the unit 220 at least to receive with the data transfer unit 244 from the measuring
instruments 230, by way of a communications link, measurement data regarding a fuel
coming from the fuel unit 106a, 106b, 106c and to control with the data transfer unit
244, by way of a communications link, the feeding means 110a, 110b, 110c for delivering
the measured fuel into the silo 104, 108a, 108b on the basis of its content model
and measurement data.
